The temperature and density distributions used within the fiducial case for each astrochemical disk model (Section 2.4). From left to right, the columns display the gas temperature (T_gas), dust temperature (T_dust), number gas density of hydrogen nuclei (n_H), and total mass density of dust (ρ_dust). The temperature and density distributions are depicted in linear and ﹩{\mathrm{log}}_{10}﹩ scales, respectively. Temperature contours are shown from 25 K to 125 K in 25 K intervals; number density contours are shown from 10⁴ to 10¹⁰ cm⁻³ in order-of-magnitude intervals; and mass density contours are shown from 10⁻²³ to 10⁻¹⁷ g cm⁻³ in two-orders-of-magnitude intervals. From top to bottom, the rows display the distributions for each star, in order of increasing stellar mass (Table 1).
